For grains and similar items, I guess it really depends on the amount of available storage on the supply side and the duration of the failure. The grains themselves might withstand the delays but the disruptions would still be present (demand side lack of availability and increased prices). The reasoning is: 1. If the usual way is to always ship out the grains, then presumably the supply side currently lacks storage facilities to store a lot of extra grain. I doubt anyone can keep such facilities around and empty "just in case". 2. Whatever the supply-side storage capacity is, it could still fill up if the stores were not emptied fast enough. And here the emptying process was part of the infrastructural failure. 3. The use of alternative transports could help but would cost more, otherwise everything would be already transported using these methods.
